I use Fiskars too. It's all personal preference. I know people who don't like spring loaded ones because it fatigues there hands after hours of trimming. I like them because they are very percise and there is no thumb hole with causes pressure points. If you have the money buy a few different kinds from the hydro store. It's like golfing. Everyone has different clubs, different swings, and different grips. Trimming is an art form.
