track and rear suspenion questions

i am pondering doing a few thing to my D7 to make it perform better, and lose weight, while not completely breaking the bank. so here is what i am thinking, what is your intake on doing these mods and are these good mods or will they make it weak or any other cons.

153 power claw: local dealer quoted me $950 for new, and read it should drop 8-9 pounds. i would also need the drivers. which drivers? and is that all?

Drop-n-roll: get better approach angle and get ontop of the powder better. probably does not lose weight, but helps deep snow performance and is MUCH cheaper than a complete rear skid.

ice scratchers: i have the wheels now, and i can imagen the scratchers will lose a little weight. i believe i heard about 3 lbs. but will they keep me running cool and any cons against taking the wheels off for some scratchers?

2010 rails: looking at the 2010 dragon brochure, it says the new rail design is lighter, and strong, but it is really as strong as the rails that came in 07-08? i have heard different stories. any idea how much weight loss i could be looking at? might not be enough lose to justify doing the swap.

So, all together, the track will gain performance and lose weight, while the D&R should increase performance. the scratchers would lose a few lbs (hopefully) while keeping me running cool, and the rails would lighten up the rear a little more too. i dont know how much the rails would lighten, but i dont want to sacrifice strength either. and i dont know if they would be worth the amount they might cost.

these are just a few ideas i thought of to lose weight, increase performance while saving a lot of money from going to a complete rear skid like the timbersled or holz.

whats your thoughts? does anyone know the answers to any of the questions i had above?

thanks guys. i thought the same thing about the rails. the new ones look sweet, but are probably not cheap and drop minimal pounds.

the scratchers.... i understand about forgetting to put them down... is it bad to always have them down? i think i would be able to remember to put them down, but i am forgetful.

the D&R would be used to get a better approach angle, but maybe i can just do the powerclaw first and see if i still feel i need the D&R. so far i have rode some deep stuff and only sunk her twice in 500 miles. so the D&R will wait till after the track and i see if i want it or not.

lastly the track...thanks for the link. are all power claws the same? or are there better ones? and green_denali what ALL did you need to change over for the power claw to work? what length? if you are longer than 155, is everything you changed the same for a 155 sled? thanks and sorry for all the questions

thanks. we jump off trail, back on to go to next spot then off tail then back on all day usually, so it sounds like a lot of flipping with them. maybe it is just easier to stay with the wheels?

what part of wyoming you from chas? im in powell

you do bring up a great point. i have not rode yet with a pro yet, kinda dont want to cuz i dont have the $$ to buy one lol. but a gret point. you guys have same track but they have better rear skid and 40 less pounds. great point. maybe a trim and screwed 5.0 track and a rear skid would be best choice. but if i dont want to spend as much, the track is probably my best bet. maybe the D&R also.

do you go up to bear lodge?
