I switched from a CH setup to the TM Warthog about 3 months ago, my findings:
Accuracy in the TM stick is way more exact. Yet, if you do not have very steady hands you might consider it a drawback. No spikes, moves through the scales in single digits, dual stage trigger ( bit heavy ) and so on. Buttons on the stick are more or less on the same spot, size and feel as the CH. Big drawback is the height of the stick. After 3 months I still do not sit comfortable.
Next thing I will do is cut a hole in my desk and mount the stick below the desk which should lower is about an inch and a half. Hope it works out....
The TM makes a proper workout out of AH. Serious, spring tension is ( felt ) ten times heavier than a CH. You get used to it and it puts in a good argument for the wife ack
The throttle is a bit of a pita. Accurate, yes, heavy, yes ( with the tension all the way back to no resistance), buttons just not where you like them. Lots of buttons you cannot use in a fighter, etc. Overall the ergonomics are, well, not available. Twin throttle is nice, you can lock it to make it a single but then the tension kicks back in. Heavy steel switches look great but are utterly useless in fighter mode due to lack of speed in deployment.
Why did I buy it? Well, my CH got a bit old and dodgy after having spend about 5 years ( stick is from 2003 ) in a box in the basement and my throttle ( Saitek X45 throttle ) was dying on me.
I wanted dual throttles and the Saitek X55 wasnt out yet. As you cant buy a throttle seperately you somehow have to.
Love the stick, especially when it will fit my height requirements. If it would be possible to buy throttle seperately, I would buy the Saitek X55 I think.
Hope it helps.
If there is no need to switch, leave it be.
