I player VE on a 5 ply all wood (YSE), I tested O7E on a 7 ply all wood (BLY Power 7). Feeling was amazing. I think the BP7 blade was doing a nice job, but I'm confident O7E was playing a decent role in that job. O7E is a natural overall upgrade for VE especially because it's not increasing sponge hardness. I cannot quantify this upgrade because BP7 is a good upgrade of YSE as well (7 ply vs 5 ply, very similar construction with same inner wood plus a much harder outter wood - Koto vs Anigre). Let's put this way, if you believe VE feels lackluster in something the O7E will give you a little bit more in that something. Price-wise a VE at 26-28€ is a lot of value for money these days that is likely unbeatable. One of the pros is that using O7E comes easy if you're used to VE because they react similarly (very controlled and consistent, medium-soft with good dwell time). I read Vega Korea might be an upgrade of VE, I'd be curious to know how VK compares with O7E.
