RE: anyone in the slick trick circle??
I am not "in with them" although I have emailed back and forth with Gary the owner over the years. Some not always pleasent, but honest and polite. I am sure if you drop him a line he will answer you questions directly. Slick trick heads have really come a long way from the first, not so great heads I tested 6 or 7 years ago to one the best on the market and they are the leader in the push for more accurate and durable heads. My own personal opinion is that if the 100 grn versions do well, you will see other weights as well.
