I thought the Cayman was a reasonable blade, with Innova Light; but I wouldn't buy one, because I prefer some of the other Donic blades.
The Dima Sawtec is a very good blade and I use it with 2mm 729 blue label and 2mm 729 tackpseed, as my main league bat. The Sawtec has very good control and the spin I can generate with 729 rubbers means I can vary speed, spin and placement, throughout a match.
A practice partner; uses a Donic Persson Powerspeed, with 2mm J O Silver and 2mm Supersonic S40. The J O Silver on the forehand is a very quick rubber and not very forgiving of a mistimed or mishit shot. It's an interesting experience using it. The Supersonic S40 works on the backhand of this blade for me, but it wouldn't be my choice on the forehand. My practice partner is also finding out that a fast set up can be harder to control in the short game and the variations of speed and spin on my serves, means I win points when he misjudges the serve
I've not tried the Epox blades, but I'd guess the Epox Control is a modern take on the Applegren Allplay and the Epox Power Allround a modern take on the Persson Power Allround. Both the Applegren Allplay and Persson Power Allround are blades I rate. So I would expect these two Epox blades to be decent blades.
The Applegren Allplay Senso V2 is one of my favourite Donic blades and the Senso V1 is not far behind. Both are versatile blades, that are fun to play with. I liked the throw of these blades, making them ideal for loopers.
One of the local coaches use the Persson Power allround, with J O Silver. It's one very quick set up and requires good technique to harness it's power and speed.
One of my teammates uses the discontinued Waldner Offensive 40 with Bryce Speed FX and Donic Quattro. It is a good quality, offensive minus 5 ply blade, with a really comfortable anatomical handle. I've used it many times and like it.
My defensive teammate uses a Donic XStrait with 2mm Vario. I find his bat a bit too slow for my liking, but it suits his game. The Donic Xstrait is a reasonable blade, which I used in 2005/2006, with Mark V mk 2. It's okay for a defender of someone using it as a first bat, but the Applegren and Persson blades; are better blades altogether.
Whilst i didn't rate Donic Vario on the Xstrait, I liked it on the Yasaka Gatien Extra; particularly for looping and driving.
