Hi Chris: As always, I enjoyed your video review of the Head IG Instinct MP. During your review, you indicated that you are looking at some more powerful frames such as this one. I am a middle aged 4.0 formerly 4.50-5.0 all-courter with chronic knee issues including arthritis and an intricate procedure so my footwork is not what it used to be and I don't always set up the way I used to. I have been playing some singles but more doubles these days as a result of doctor recommendation. My current stick is a Youtek Radical MP customized to be a little heavier for stability and more headlight than stock. My question are how does the Instinct perform for doubles and would this stick be a good alternative in my situation to my Radical? Thanks.
