I've got the OL-5019 without rheostat and with a 4X lens. I actually prefer the slider to the dial. Only thing is the dial does 1 yd and the slider does 5 yd increments - however OT2 makes me a perfect tape in any increment I want. I recently got a wild hair (I've changed and screwed up a lot in the last few weeks leading up to opener - I do it every year) and tried some multi pin sites. Completely reiterated why I went to the single pin and HHA to begin with. I bought an IQ and really like and saw benefit to the retina loc. But, trying to shoot looked like I was looking thru a barcode and the build quality was just not there. The retina loc would lose its zero about every 10 shots. My next try was the Trophy Ridge React V5. I opted for the vertical multi pin since I was used to a single pin. This one was ok but even vertical multi pins gave my eyes trouble. Also another case where the build quality of the HHA has spoiled me. I discovered a new accessory this past week that has answered everything for me with the HHA and it's cheap. HHA makes the sp-50 (part #) that allows you to bottom out your slide at 20 yds which is what I wanted but also allows infinite adjustment if you make a peep change, rest or whatever to you can keep the same tape. I love it. One of the reason I even looked at the multi pins was I was tired of burning good tapes. This little gem was $11.99 at Lancasters.
