I have noticed that the new slimline wagtail is a bit stronger on the blade tip so if you do the new dog-ear
it won't break as easy as the old one.
If you havn't tried it before you might be suprised how well it works. The accuracy that can be achieved is amazing with hardly any detailing to do. Tried an unmodded version just to make sure I wasn't mistaken.
Massive difference.
For pole-work this is a vital mod. The only bit of detailing to do is the top edge usually.
