Here’s an analysis of the horse race:

1. Plumette
   With the highest total rating of 343.4, Plumette clearly leads the pack. She has two Course & Distance (C&D) wins under her belt this year and a good third place finish on this course just three weeks ago. With her proven track record at this course and consistent performances, Plumette remains a strong contender for this race.
2. Triggered (IRE)
   Triggered follows Plumette with a total rating of 327.7. He demonstrated his form with a win at Lingfield and a commendable second place finish on this course. Notably, he clinched a victory at Chelmsford City just a fortnight ago. His solid credentials make him a strong contender for the top spot in this race.
3. Ikkari (IRE)
   Despite a mediocre total rating of 284.2, Ikkari stands third in our list. She didn’t fare well on her handicap debut at Lingfield and has some points to prove. However, she showed promise on her single encounter with Tapeta when she was runner-up over Course & Distance last May. After her recent wind operation, she is an outsider who could potentially surprise.
4. Little Earl (IRE)
   With a total rating of 254.7, Little Earl is next on the list. While his mark continues to drop, he didn’t perform poorly when increased to 7f at Southwell last time. However, he needs to bring something extra to the table to secure a win in this race. The addition of first-time blinkers might be the change needed to bring out his best.
5. Dolly Gray
   Dolly Gray has a total rating of 251.6. She didn’t make a significant impact in her handicap debut here last October. Still, she was a promising second in a C&D novice last September. As a lightly raced horse, there might be more to come from her.
6. Spartan Fighter
   Spartan Fighter holds a total rating of 245.8. He won two consecutive races at Newcastle last year and now stands at a dangerous mark. He showed some sparks in his previous starts but disappointed at Southwell last time. If he can overcome that poor performance, he might just live up to his potential.
7. Tom Tulliver
   With a total rating of 224.6, Tom Tulliver’s rating doesn’t promise much. Despite that, he’s on a competitive mark based on his year’s best Southwell Tapeta form over 7f/1m. He might have a chance if he can rebound from his heavy defeat at Doncaster last month.
8. Poet
   Poet is at the bottom of the list with a total rating of 180. His mark continues to drop, but he hasn’t shown any signs of taking advantage of it. It seems hard to fancy his chances in this race.

In conclusion, based on the total ratings and recent performances, Plumette and Triggered seem to be the top contenders in this race. Meanwhile, horses like Ikkari and Little Earl have the potential to cause an upset given the right circumstances. It is advised to keep a close eye on all the contenders as horse racing can often be unpredictable and any horse can surprise on their day.
