I started lifting in the 70's nothing but raw and competed in the late 70's. I tried shirts in the 80's did not like them and besides that had no crew to help or teach me, or internet, so with little help I went back to raw and belt. Then in the 2008 I got some real suits and shirt and tried it again, big difference but raw was still an option and I competed in raw comps for a couple of years.
Now I have a crew and these guys only did geared lifting in none the less multiply! So out to buy $300 shirt and $300 suit, $200 briefs and better wraps for knees and wrist. Been training in gear (multiply) for over 2 years and plan to have my FIRST multiply meet in a couple of weeks. It is hard in gear, and you just don't put it on and do 200lbs more in each lift. It is special form special technique and if you are not doing it that way it is over.
I continue to train raw and competed and I know my gear lifting has helped me in raw squats. Since I've used gear I have competed raw in a few meet. My raw squat has increased 120lbs in competition lifts and I'm over 50 at 240lbs and I'm not talking 300lb squat to 420lb squat more like over 500lb to over 600lbs.
So do I think there should be more raw comps? I don't think there is a federation out there that does not have a raw division so that is a mute question.
Shoud geared lifting (single and multiply) be forgotten? No, it has its place and this should still be a division for those who have crews and want to feel the heavy weight.
Geared lifting is special, you need a crew, good squat racks or a mono lift, competition bench, power racks to name a few of the special equipment to lift on.
Lifting raw you can do at almost any commercial and you can pretty much train by yourself. I am not saying you should just that you can.
Geared/Raw, you will always have a debate but each has its place in powerlifting but I feel that each helps the other.
