sledneck, i was talking about the front geometry not the rear skid. from what i see/heard you are correct on the 09144 skid use.
ramcharger, i think you will be fine with the 155. i doubt it will be too much to handle. i would save your money and just cut the stock track down as mentioned on other threads. the life of the track won't change. if anything it will increase but probably not noticeably. fwiw, i cut my 09 track per f-bomb's instruction, have ridden it like i stole it and am missing zero lugs and have no track damage.
then again, 660 setup's are very B.A. if it means anything both jack and chris from carl's chose to run 660s this year rather than 800s. they are supper fast and a kick in the *** to ride. but it probably won't win a flat out hill climb comp but at 165 geared up you will not have an issue keeping up with anyone, anywhere. plus it wouldn't hurt the pocketbook nearly as bad. good luck, enjoy.
