R.I.P. control vs. Isospeed

[rofl_copter3]

I know Isospeed makes both strings, but is there a difference in performance between the RIP and say the control/professional classic or new version either one???

Just trying to find out why the price difference...

I use RIP Control. I never tried Isospeed. I can definitely tell you, though, there are major differences between the two. Look at the structure:

This is RIP Control:

This is Isospeed Control:

The polyolefin ribbon is helically wrapped around RIP Control, kind of like a spaghetti string. With Isospeed Control, it is a homogenous wrap included in the main structure.

RIP Control has a rather stiff/harsh feel, though it's still quite comfortable to the arm. It has very little elongation. It maintains tension better than any other string I've tested.

Other reviewers have commented on the softness of the Isospeed strings, and they have a reputation for losing tension.

The isospeed is very soft indeed tho the classic has a bit of a crispness to it. As far as tension the isospeed does drop the level off and stays very playable til it breaks.

Is rip pretty low powered felt a multi?

Isospeed Control and RIP Control play nothing alike.

Yes, Head RIP is a low powered string.

This is interesting pictures. I thought Isospeed was 100% polyolefin while RIP
control was polyolefin + nylon. They are both mixture of polyolefin + nylon then ?

I don't work for Isospeed, so this is merely speculation. The chemical description is polypropylene. That doesn't really narrow it down much because the polymer structure could be anything. So it's possible that the wraps are not the same exact polymer.

I think Isospeed Control is more closely related to RIP Feel (the cross string component of Intellitour and Intellistring). I've heard they are similar but not the same.

Yes, Isospeed was closer to RIP Feel.

I always wonder how these strings with non symmetrical cross sections could play differently just depending on the string orientation in the racket.

That must be why you get random power surges with RIP Control! LOL

Actually, it doesn't make much of a difference in theory for RIP Control because of the helical pattern, but I've heard other stories of random losses of control so maybe there's something to it. Personally, it doesn't seem to affect me too much, but I've been using mostly hybrid setups, so that probably helps.

 

[morten]

do not mix up isospeed control and control classic(old one, much better)

Head Rip control now is priced $9.50 at TW.

I hear this often.
