Soft to medium, mostly softer as i can get more control and i have enough speed to add to it.
The rubbers that shines so far on my BH for a while are:
1. Rakza 7 Soft
2. Tenergy 05FX
3. Xiom Viga Europe
So i am thinking about something similar to above if available at better price, otherwise i will stick with one of above.
Ok, so you and I like the same thing.
My suggestions:
1. Xiom Vega Asia or Japan. Both are a bit harder than Xiom Vega Europe. And both are a bit more catapulty than Europe. I find Japan's top sheet to be softer and slightly better quality. But I like both. These two would be the most budget friendly options.
2. C-1. I find C-1 to play closely with Rakza 7 soft. Maybe slightly less catapulty. C-1 is a very good rubber.
3. Donic BlueFire M2. I just recently started using this rubber because, well, it comes in blue. I like it so far. I think it is slightly harder than Rakza 7 soft. I have a sheet of M1 that I have not installed yet. By pressing on it, M1 reminds me of G1. M3 might be too soft for you. You can try M2 if you want.
4. Rakza 7. Obvious choice if you like Razka 7 soft and you are ready for a harder sponge. Personally, I have a sheet of Rakza 7 regular and a sheet of Rakza X regular in original packaging. I am not ready to open either packages because my BH is not ready for them yet.
5. Tibhar EL-S, EL-P or EL-D. So I have played with MX-P, MX-S, EL-S, and FX-P and FX-D. I like the series ok. They are slightly more expensive than Rakza 7 soft and C-1. Some people complain that the rubber do not play well after a couple of months. I don't feel that way though. FX-D and FX-P are fine. They are now too soft for me. MX-P I had one sheet before and I did not like it. MX-S is too hard for my carbon blade and it works wonderfully sitting on the BH of a 7-ply all wood blade. I have had two sheets of EL-S and I like them. They are just about the right hardness right now for my BH development. The Tibhar Revolutions series seem to be more catapulty than G-1/C-1, Xiom Vega Series and Rakza series but less cataputly than Tenergy fx series.
In summary, I don't think you need to go Tenergy or Dignics yet. There are plenty of ESN rubbers for you to upgrade to. For example, I have played with Xiom Vega Pro and Xiom Vega X. They are both on my spare blades right now. Just too hard for me at this point.
