Speedy, congratulations on your Revo -- it's a great little sailer -- for a kayak!
I haven't had any mast bending problems yet, but in stronger winds, I don't cleat off the sail so I can have a quicker response to the gusts.
If your sail shape is a little open on the leech and your sheeting position is here...
you have several options to move it forward, closing the leech and improving performance. First, you can go here by replacing the screw-in cleat with a screw in padeye (note also the easier to use rear handle position):
(Note, this is not as strong as either of the other styles shown -- test it first if you go with it) You can also reverse it easily if you don't like it -- no holes.
Or, you can screw in this style of padeye anywhere you like like (Adventure shown):
Or, you can rig your sheeting block up on a trolley and experiment or easily change the position (Adventure also shown here):
This should be less stressful on your mast as well.
If you plant your downwind foot firmly in the scallops it will tend to keep you in the cockpit even better and let you hike out more. I tend to plant both, especially with the Adventure!:8)
