No I have not used the Velco unit, but looks very interesting.

I take the heavy laces out and use OLD tan colored braided flyline.
I take care to tighten carefully and not put the grommets out.
And after I shoot, I tighten the line and then tuck the line under the rear of the flap. And on and on till it gets very tight with no movement. Then all is well.

For the minimum expense, EITHER sure would be worth a try.
