One other thing to realize... not all helmets are the same shape. I love my Tacks 910 and wore V08's and 4500's before that, all are made for oval shaped heads. I tried a Resistance/710 and one of the Bauer IMS models but they were too round and never felt good on my head. So finding the right shape is a big help... with that said, the Tacks 910 is extremely comfortable and has basic adjustability but there are some Bauer models which offer the traditional front/back adjustment as well as a side to side adjustment (I had to get one of those for my son since he had a big old round head and everything else hurt lol, I just checked and its a Reakt 150 so that might be worth a look).
