Do yourself a favor, stand in front of your press, lower the lever all the way down, let go, stand up straight, then look down and realize just how far you have to bend over to fully actuate your press. Then, while still standing up straight, use a tape measure to measure from the center of your closed fist to the center of your current handle......that difference is where the Ergonomic lever comes in.
The forward offset design of the ergonomic levers snug you into your press, position you perfectly to see your powder charge before placing a bullet, keeps you from bending/leaning over time after time and keeps your comfortable through-out your reloading session. The roller handle is super smooth and a dream to use. Custom built levers to your spec's are no problem.
Your back will thank you! But don't just take my word for it. Ask around in the popular firearm forums.
All Inline Fabrication products feature a lifetime "No worries" warranty. Also, if you try a lever, and you two just don't get along, you can send it back for a refund. (Minus shipping to be fair.)
