I prefer the Lyra brush, I agree it can be difficult but good lighting helps. I also like the soft bristles as I don't feel that it can ever cause any damage.I would recommend trying to overcome and issues you have and stay with it. JMHO.
Lyra SPT and poor eyesight
Having come from LP9, which has a nice broad brush, I'm having trouble applying SPT on my new Delos. Is it advisable to substitue a larger brush, say like the LP9 brush (cleaned and sterilized of course) or is that a no no? I remember using SPT a few years ago and it didn't seem that the brush was so difficult to use. It can't possibly be that I'm getting older :)
