After various Bell and Shoei helmets, I had a ROOF Daytona for many years - fantastic, really comfortable, good visor action, watertight, etc.
I then decided that I needed to buy a new one, purely due to the age of the ROOF, so after trying various makes and styles (in the shop only), I opted for a Schuberth C3 - flip front, lightweight, flip-down tinted visor etc. and great quality.
However, after riding for less than an hour, it was pushing on the sides of the top of my head - quite painful, which very soon became bloody excrutiating! No obvious reason why, so I persevered and used it a few more times, hoping perhaps that the padding would 'settle' and all would be well. No!!
I just couldn't get away with it, so it went on the shelf in the garage and I reverted to my earlier liking for Shoei and bought one (can't recall the model). Again, it felt fine in the shop, but in 'real' use, I have exactly the same problem as the Schuberth

AAARRGGHH!!
I subsequently sold the Schuberth and still use the Shoei on occasions (shorter rides....), but for longer rides I still use my old ROOF (now about 12 years old).
So, what to do?? I have yet to find a dealer that will 'lend' you a helmet to try on the bike for a decent length of time so you can a feel for it in a 'real life' situation (noise, visibility, comfort, etc.). The old ROOF factory was burnt down, so any Daytonas still on the shelf will be old stock; the latest ROOF designs are a possibility (as are a few others), but it's back to the problem of being able to try them for more than two minutes in a shop.
(and I don't have a bottomless wallet ?$?$?$!)
Suggestions welcome please!
