Hey clintlee,
I use both.
I find it easier to tweak a recipe with small amounts, like 500g, of malt when its dry, for larger amounts I usually use liquid.
I have read that the LME can sometimes go bad, maybe give some off flavours, but I have never experienced this…..hope I never do ! (always check use by dates on tins). There is also good variety with liquid malt.
DME stores well, is easy to use.
Its ultimately up to you anyway, try both and find out what works for you.
Have fun with it mate !
