I’ll give my opinion, but that’s all it is (and it’s only worth about what I charge for it). Picks are kind of like strings, different people have different tastes. I have multiple Wegens, a blue chip and tortoise to compare. I don’t have a pro plec. The Wegens are absolutely nice picks and the Wegen BG pick is about $4. Well worth the money. If you want a real rigid pick get the 1.4 thickness. The 1.0 has a bit of give. The material of the Wegen is fine. I actually prefer the material of the dunlop Ultex (about $1 per pick), however, the Wegen has the nice little grip holes and they have a nicely shaped bevel.
The blue chip are nicely crafted (nice bevel) but what sets them apart is the material. It has several properties that make it special. First, tone wise, they are great, they seem to have a wee bit more pick noise than tortoise but are otherwise very similar. It’s a darker tone than most, and some may not like it (but I do). Second it gets through the strings well. Third, they are all but indestructible. I have been playing one daily for 6 months and it has never needed edge maintenance (Wegens will need to have the business edges polished up from time to time). I only use the tortoise on “special” occasions (mainly recording) as tortoise does wear. Lastly the Blue Chip has a tackiness that makes it want to stay put in my grip. Tortoise does the same thing. The BC is as close as I have played to tortoise, and it is actually superior in durability.
I would highly recommend Wegens for anyone to try. For $4, it is tough to beat. I find a BC to be worth the money, but when it’s $35, it’s not going to be for everyone. However, assuming you don’t lose it, I can’t imagine ever wearing one out. If someone is on a real tight budget or loses picks often, the Dunlop Ultex is a nice alternative and with a little bevel shaping is a nice playing pick.
