That's another thing I have read as well. All I have experience with are 2 MOA dots (Aimpoint Pro & Vortex Sparc)...curious to see the nicer dot 4 moa or larger provides
if your planning of using the T1/H1 within 100 yrds( 10.5 -12.5 bbls)with no magnifier at the rear, then I would go with the 4moa, with a magnifier then the 2moa would be ideal. this is my personnal experience and opinion, Im not an expert or a PRO.
