I'd suggest a little experimenting with some different/more wrap. You should be able to have more teeth available on the clamp for more tightening. Which gives you more options for varying pressures during your sets. Don't get too locked into one method. Play around! Don't stop at one clamp either. When you're comfortable, stack another clamp on top. You need to use a wider wrap of course. Last but not least, don't forget about my clamp

Lots more options there with adjustment, pressure levels, and such.
