frame sliders

Hi all im looking for some opinions on which frame sliders would be recommended. I would like to not have to cut the plastic if possible. also where you would suggest to buy them.
Thanks

if you don't cut the plastic, then the pucks won't protrude enough to offer any significant protection i don't think.
i'd say go with cyclecat's.
if you don't want to screw with your stock plastics, get some shark-skins or or used stock bits off the classifieds here or off eBay to hole-saw. remove the pucks when you want to put your stock bits back on.

For a track bike or street bike?

For the track, I went the route of an Axel Jax clutch & water pump cover, bar end sliders & Woodcraft rear sets. Therefore, all contact points are secured... I didn't see the need for frame sliders with all of the above components in place, but I could be wrong..... Someone with far more knowledge can probably offer an alternative recommendation...
