Just quickly the main route options.. they aren't huge but probably save 5-10 minutes..
1. illegal use of inclines in quarries.. banned and would be DSQ for using them..
2. Elidir Fawr... I take the paddy line.. others swing via the gully..
3. Short cuts on garn.. the path zigs..
4. Glyder Fawr.. stay left and directish then back right and you pop out nearer the summit than following path..
5. Descent... drop left off the path..
6. Lliwedd.. traverse peak 1..
7. Snowdon.. direct line to summit.. East ridge.
8. Shortly after the summit direct to the ranger.. later on follow the fence and grass rather than ranger
9. Top of cynghorion.. straight line the summit..
