Week 6 of the Alaska high school football season finally brings some sweet showdowns -- the top four large-school teams in the Alaska Sports Broadcasting Network Poll clash this weekend.

Palmer (5-0), which moved up one spot to No. 1 after last week's 41-14 Railbelt Conference victory over Colony, faces No. 3-ranked North Pole (5-0) in North Pole at 7 p.m. Friday in a battle of Railbelt co-leaders.

And No. 2 South (4-1), which lost in California last week, takes on No. 4 Service (4-1) at Anchorage Football Stadium at 7 p.m. on Saturday in a Cook Inlet Conference rematch of last year's state championship game won by Service.

No. 5-ranked West (4-1) entertains Dimond on Saturday at 12:30 p.m. at AFS.

All five teams in the large-school poll are unbeaten in Alaska this season --Service and West each lost a season-opening game in Hawaii but have run the table in Alaska. South, Service and West are each 4-0 in CIC games and have basically clinched three of the CIC's four berths to the state playoffs.

In the medium- and small-school poll, the top three remained the same -- Eielson (4-0), Soldotna (4-1) and Nikiski (3-1). Monroe-Catholic (3-1) moved up one spot to No. 4 and Thunder Mountain (3-2) fell one spot to No. 5 after falling 27-20 in double overtime at Skyview.

Eielson last weekend beat Nikiski, 57-48, on the Peninsula.
