Just my 2 cents. I rode trials 20 years ago and just got back into it 4 months ago. I have done 8 contests so far and done well in each of them. I am 45 as of today and the best adjustment I made on my bike was to raise the bars 1/2". This made me more comfortable allowing me to ride longer as well as better. I say try it if it does not work for you by all means change it back. For me it was night and day difference on my back.
