I'll add Ingar Hvamstad onto that list. Rode for Poole in 1996. I believe he was initially Lars Gunnestad's mechanic. Sadly he took his own life not long after.
Talking of Lars Gunnestad his son Daniel came very close to riding for Somerset in 2009. Daniel came over to ride for the Team Viking touring team that year and impressed the promotion during a second half there. They had to cover injury and needed a 5 point rider. In the end it came down to finances and logistics and instead they opted for Jari Makkinen.
