hello brother merhaba hocam in turkish with your permission
writing because of wanted to make you get an idea bout the properties of the limba and koto layer..as i know timo boll alc m.maze spirit are nearly the same ones which you can add them in a type of blade and viscaria is slightly different with is central balse layer i think this should be the main difference ..if u want me to compare vis with the others which i mentioned at top; vis feels a little bit softer but more powerful in terms of my feeling
trajectory is longer and higher as my friend said before i have the same statement and whats more vis is more dynamic mid and far distance from table than the other alc things it is very different however they all categorized in the same group i both used them with same rubber tenergys and vis is much more lively and make you feel that the rubber is fresher if i were you i could give a chance for vis i have just bought it and im satisfied enough although it is a classic and contain elder materials and methods to be prepared due to its producing time period it still rocks and provides anything you will need just choose the right rubber and give it a little time to getting used of it
P.S:despite of being faster(vis) it felt more controllable near to table its strange but true i also tested and experienced it but in the mid and far distance it is already fast enough for every type of spin loop drive etc you wont regret it
