what shocks should I use

i will have my new wheels and my wheel spacers in the next few weeks. and will see how much wider my 250ex will be, if it's not wide enough then I will modify the a-arms to get the rest of the width that I need. and I wanted to know if you guys could tell me what shock i could get for it that would be longer and ride better than the stock 250ex shocks. I have it narrowed down to two companies elka shocks or the fox air shocks. which shocks would be better and give my 250ex the best ride quality. thanks in advance for your help you guys are great.
