Another garlic question

I planted Solent Wight last Autumn and they did quite well although the bulbs were smaller than I put in.
I've saved several to plant this year because I know they're disease free and buying new is pretty pricey!! Will the new bulbs be smaller still?
I didn't use potash last year but am planning to next Spring having read the other garlic post! Might this improve the size?

We bought bags of 5 bulbs for £1.30 off the local market last year and got a really good crop from them.
