However if you haven't cycled the old railway line Dolgellau- Barmouth then you have missed one of the finest cycle tracks in the UK IMHO.
Briwet is a vital link on the West coast route.
I would second that. I would also say that with respect to all the comments about recognised routes there is a lot to be said for an absence of planning and spontaneity. I like to plan a vague sort of direction but leave the day to day route selection open to what takes my fancy on the day according to weather, how I feel, what the locals say etc.
Having lived in Mid Wales for 25 years I'm a little biased but any time spent touring in that area will be time well spent. Enjoy yourself.
