You cannot find E4 anywhere. Closest blade to Violin I found is VICTAS Euro Feeling Off- that I have on my second bat and I like it a lot. For Anigre I have Yasaka Sweden Extra that I use on my first setup, it's an awesome blade, my coach was surprised of how good this is for the price. I like...
I found Vega X getting better after weeks. Likely because I'm used with soft sponges. I quite liked that rubber, apart for pushes that I found difficult at my level.
My son is 2 yo and he fools around the house with a bat and mimicks the FH loop stroke saying "top top top". He's also doing the FH loop brushing (actually hammering like a blacksmith) the rear wheel of his (upsidedown) bike. Now that I've seen this video I'm going to intensify the training...
It makes sense to me that powerful players look for control over speed. If your speed is already enough to score the point majority of the times, you don't look for more speed but rather control.
It suggested my current FH rubber, one rubber I don't know and the one I'd like to try the most. Definitely a better result than before. BTW you cannot mandate to rate all rubbers because people might know nothing about one of the recommended rubbers, so their rating would be potentially misleading.
No direct experience here, but currently I'm training with a veteran like the man you're talking about, he has shakehand grip and uses a ~30+ yo blade from darker. It's 5ply, 3 wood and 2 carbon. The blade is called Max Control and believe me name is very adequate. It's slow as hell due to age...
I use Vega Europe and FX-S on my blade and although FX-S is 40 degrees it feel much harder than Vega Europe due to the top sheet. It's very likely that Vega Europe has also a very soft top sheet.
Omega VII Euro is just awesome. My coach has it on a Bfly Power 7 and feeling was superb. Unfortunately an Omega VII Euro costs almost double than Vega Europe!🤣
TBH my setup was made following suggestions from my coach. He always says power is useless without control. I'd say it's popular also at beginners level at least in a country like mine where TT community and history isn't too much developed.
Vega EU is great also on 5 ply all wood. I use it on Yasaka Sweden Extra and control is top notch. It lacks of speed, but if you use 5ply all wood and soft rubbers like me, speed is definitely not the main focus of the setup.
