I need new knicks.

My wife has always made them but really I don't find them that great as they always catch on the seat when getting back on after standing for something tricky downhill.

Probikekit has lots of different deals. eg
Team Giant 8 piece for $36
Prorace 6 piece for $28 and
Nalini 6 piece for only $20

Anyone know how these compare to the Groundeffects Sputniks for $79 (which I haven't tried but look good on the website). If the Nalini 6 piece are any good they seem to be a very good price at the moment.
