Training should be as much about fun/enjoyment as it is progression. If you need a mental break from the monotony of low reps or just have a wild hair to try the high reps, go for the higher reps. Just accept that changing things could have a negative consequence and set you back... OR it can have a positive impact.
I'm all for sticking to what works, but sometimes you need to take a step into the dark and experiment a little.
If you do choose to go for high reps, drop a some weight so that the first handful of training sessions are easy-moderate and add weight from there. That and make sure what ever you choose you stick with it for some time. Jumping from program to program in short periods of time does little.
