Q: LH43 alternative for ZD25 F2.8, quality wise

Hello,

did someone who uses Zuiko Digital 25mm F2.8 lens tested hood / no-hood performance?

I use this lens, and haven't noticed degradation of image quality when I use Oly LH43 hood attached on the lens.

Maybe larger hood would yield some better results? I've seen eBay full of different hood models for 43mm thread, some of them rather deep which might work nicely, but I don't want to throw money.

Comments appreciated!
