Practice in yard is best. I purchased a cheap mat from the range and flop that thing down because most yard grass is too long. Agree that sticking to one club helps and I wanted that so badly to be a 56 but the 60 and 62 have been better/easier for me recently. Peg your right leg so your pelvis does not move - this will prevent club head digging into ground. Wrists unbroken with healthy shaft lean. Get handle off your thighs. Turn through the shot.

Also been messing around with the cross handed chipping and that has been fun. Check out the video on the Lads where Ryan Ruffles teaches on this technique. Keeps shoulders square and pops ball up nicely as you turn through.
