They're horrid on every bike ever. What bike have you got, I know I already replied but if you have a short comp bike with fairly extreme geo (Koxx Hoesel, Monty Kamel) then I'd get Try-All rage, if it's a longer comp bike (Echo Lite Disc, Koxx Hydroxx 2), I'd get Monty PRs and extend them an inch either side, if you have a very long street bike (Zona Zip, Long Python), I'd get TrialTech.
