It really depends on the company, and what their insurance requires. It all legally counts as time. From my experience, a lot of jump plane places wanted X amount of high performance, or 20-30 hours of time in type, etc. And a lot of glider towing places require a fair amount of tail wheel time, 25 hours seems common. If you can meet those 'odd' requirements, they probably won't care that you have a bunch of time in helicopters.

There were two nearby skydiving places I was trying to get work at, and one required 30 hours of 182 time, and the other 25 hours of 206 time. Once I finally crossed the 1000 TT threshold they were finally willing to waive those requirements.
