I don't think you should be "thinking" or contacting your triceps, that will cause you to tens up, over grip the racquet, arm the ball and to over-think things. First you think your triceps straighten the arm then bicep to bend it? Too complicated if you ask me and that is where I take issue with this thought process. It disregards where the ball is, you basically implying that you need to straighten the arm to hit better forehand and the ball is an afterthought that you adjust to later. I think it's a bit backwards to be honest. You need to move the contact point first and by virtue of doing that, your arm will get straighter. Without doing so and by concentrating on the arm, you will not time the ball correctly, you will shank a lot and generally you will just look awkward out there.
The best way to see if straight arm forehand is more comfortable for you is to have someone feed you some balls and attempt to move your contact point out in-front and to the side a bit. By consciously attempting to make contact further away from your budy, your arm with straighten. You can then see if this is more comfortable or not by making your opponent/coach to feed you tougher balls, some high forehands wide, some short balls and maybe a few slices. Getting a good form on balls fed right too you is half the battle or half the experiment.
"This is what I feel is natural or maybe it comes naturally to me cuz this the only way to force your arm to your back" - I would not put it in these words, you don't force your arm back. At least that is not the mental image I would like a player to have. I would rather have him concentrate on contact with the ball and have a mental picture of accelerating smoothly through the contact, instead of worrying if he force his arm back enough.
If these mental pictures work for you - then great, I really do mean that, it is just not what I found to work, via trial and error.
I was hoping for a more serious response. Oh well.
